Władysław Mazurkiewicz (serial killer)

Władysław Mazurkiewicz (January 31, 1911 – January 29, 1957) was a Polish serial killer from postwar Kraków, who also owned property in Warsaw. His economic standing and polite manners in Stalinist Poland earned him the nickname "the Gentleman Murderer" (elegancki morderca), also "piękny Władek" (the Handsome Władek).
Mazurkiewicz was charged by the prosecution with six murders and two more attempted murders. He was convicted of killing four men and two women including Wiktor Z., Władysław B., and millionaire Jerzy de L. along with his wife Jadwiga de L. and her sister, Zofia S.. He was tried by the regional court in Kraków and sentenced to death on August 30, 1956. He was executed by hanging six months later on January 29, 1957, two days before his 46th birthday. According to various rumours, Mazurkiewicz might have been responsible for as many as 30 murders, which were never confirmed. However, he himself pleaded not guilty, and claimed in court to have been beaten and blackmailed during interrogations.

His mother died when Mazurkiewicz was 3 years old. He grew up with his father who was a printer by profession. After graduation in the newly reborn Poland, Mazurkiewicz enrolled at the Jagiellonian University department of law but dropped out. He was drafted during the September campaign. According to his own testimony, during the Nazi German occupation of Kraków, Mazurkiewicz made friends with the human resources chief of the local Gestapo, Rudolf Arnold, who issued him the Kennkarte of a Gestapo friseur which allowed him freedom of movement. He made a living by trading gold, money and diamonds illegally. His first murder victim was yet another gambler Wiktor Z. poisoned by tainted tea in December 1943 and stripped of 1,200 dollars. After the war, Mazurkiewicz obtained a position with the Polish Red Cross, and worked as wine seller and driving instructor. In September 1955 he shot and wounded Stanisław Ł. in Warsaw. His victim survived and contacted the police which led to his arrest and grand-scale investigation into his own crimes. His revolver was found, and he was recognized by the surviving victims. Nevertheless, Mazurkiewicz claimed in court to have signed an admission of guilt under torture.
